摘要

A thermo-mechanical protection device, applicable to motors or electrical appliances, essentially characterized by the fact that the line feeding the motors or electrical appliances passes over thermostatic blasts, as many as phases, surrounding them through some suitable resistances, whose resistances provide the heat of expansion to said bilamina, which when exceeds the expected type temperature, forces these bilets in their uneven expansion to push an axis, making it turn on itself, with whose rotation the triggering is caused of a sear, which is the one that maintains the supply circuit of a safety relay or similar of the installation, the circuit of which is then broken.
